International Conference on Indoor Positioning and Indoor Navigation (IPIN)

The advances of electronics provide options for improved monitoring of patients in clinical environment. Medical applications like blood pressure monitoring require precise and wireless altitude measurement in indoor environment. An error of more than a few centimeters bears a risk of mistreatment of patients. Furthermore, user requirements like small form factor, usability and robust operation are important in the medical field. Existing evaluations of indoor positioning systems focus on accuracy analysis of x- and y-coordinates, not on the z-coordinate (altitude). In this paper, we define evaluation criteria for altitude estimation in medical applications. We compare an Ultra-Wide-Band indoor positioning system, an optical Microsoft Kinect camera system and our own development of a wireless barometric sensor against these criteria. We present a comparative measurement setup, results and a final evaluation of the three systems in an indoor environment.

In this poster we present the electron beam heating technique – a technique that is capable of profiling the thermal resistance along a single nanowire with a spatial resolution of better than 20 *** working principle and experimental set-up of this technique are presented,followed by several research findings using this technique,such as the spatially resolved thermal conductivity along a Si0.7Ge0.3/NiSi0.7Ge0.3 heterostructured nanowire,and the interfacial thermal resistance(ITR) across the Si/NiSi2 interface embedded in a Si/NiSi2 heterostructured *** the latter part,we found that the ITR does not change even for adjacent interfaces as close as 50 atomic layers.

A search for heavy pseudoscalar (A) and scalar (H) Higgs bosons decaying into a top quark pair (tt¯) has been performed with 20.3 fb−1 of proton-proton collision data collected by the ATLAS experiment at the Large Hadron Collider at a center-of-mass energy s=8 TeV. Interference effects between the signal process and standard model tt¯ production, which are expected to distort the signal shape from a single peak to a peak-dip structure, are taken into account. No significant deviation from the standard model prediction is observed in the tt¯ invariant mass spectrum in final states with an electron or muon, large missing transverse momentum, and at least four jets. The results are interpreted within the context of a type-II two-Higgs-doublet model. Exclusion limits on the signal strength are derived as a function of the mass mA/H and the ratio of the vacuum expectation values of the two Higgs fields, tanβ, for mA/H>500 GeV.

Several extensions of the standard model predict associated production of dark-matter particles with a Higgs boson. Such processes are searched for in final states with missing transverse momentum and a Higgs boson decaying to a bb¯ pair with the ATLAS detector using 36.1 fb−1 of pp collisions at a center-of-mass energy of 13 TeV at the LHC. The observed data are in agreement with the standard model predictions and limits are placed on the associated production of dark-matter particles and a Higgs boson.

In this work, CMOS-based tactile sensors using oxide as the sacrificial layer was demonstrated. The multiple metal layers and dielectric layers in the backend of CMOS processes were used to fabricate the moveable membrane of capacitive-based tactile sensors. The sensor was fabricated by the commercial 0.35 μm CMOS process and our self-developed post CMOS oxide etching. Three different via designs were proposed to adjust mechanical strength of the membrane electrode. A multivibrator circuit was utilized to decrease the parasitic effect of the capacitive sensors. The tactile sensors with point-type vias showed the best sensitivity of 2.65 Hz/mmHg with the dynamic range 0-388 mmHg. © 2013 IEEE.

The pronounced variation of the optical reflectance R of nanometer thin VO 2 films with temperature T at the phase transition recently has triggered interest in the development of compact thermo-optical sensors that utilize optical fiber technology. Its immunity against electromagnetic interference effects makes this approach suited for an optical detection of local areas with increased temperature, i.e. so called hot spots, inside of high power transformers. Optical reflectance of thin VO 2 -films as function of T throughout the hysteretic phase transition is reported in this work. A modified version of the Preisach hysteresis model is utilized, and combined with experimental optical data. Suited VO 2 film thickness values and wavelengths range for optimum sensor operation can be extracted. The achievable temperature range, as confirmed by experimental observations, is consistent with requirements that apply for power transformers of the first group, according to NBR 5416 (ABNT).

A search for the dimuon decay of the Higgs boson was performed using data corresponding to an integrated luminosity of 36.1 fb−1 collected with the ATLAS detector in pp collisions at s=13 TeV at the Large Hadron Collider. No significant excess is observed above the expected background. The observed (expected) upper limit on the cross section times branching ratio is 3.0 (3.1) times the Standard Model prediction at the 95% confidence level for a Higgs boson mass of 125 GeV. When combined with the pp collision data at s=7 TeV and s=8 TeV, the observed (expected) upper limit is 2.8 (2.9) times the Standard Model prediction.

Recently, a method for estimating permittivity distributions was reported. The method combined a numerical technique (Finite Element Method) with Genetic Algorithm (GA). However, methods for estimating the distribution of permittivity have not yet been established. The purpose of this study is to obtain experimental data in order to improve the estimation method. We measured capacitance and electrical potential of plural points when an acrylic rod is placed in various positions within a measurement system. © 2013 The Institute of electrical Engineers of Japan.

Fast restoration of warped document image based on text rectangle area segmentation

Journal of Software 2013年第5期8卷 1162-1167页

作者： Hsia, Kuo-Hsien Lien, Shao-Fan Su, Juhng-Perng Department of Computer Science and Information Engineering Far East University Tainan Taiwan Graduate School of Engineering Science and Technology National Yunlin University of Science and Technology Yunlin Taiwan Department of Electrical Engineering National Yunlin University of Science and Technology Yunlin Taiwan

The warp problems usually make the documents being hardly recognized. Specifically, when we copy a page of a thick book or bound document by digital photocopier, the resulted image is usually warped because of the thickness of the document. We focus on this problem and propose a fast method to restore the warped document image in this paper. The text rectangle area of the document is one of the features of a document. The morphological operation is utilized for text rectangle area segmentation. The DLT method is used to compute the mapping relations between the warped document and the non-warped document. In experimental results, the proposed method works on high resolution image very quickly. The warping text and the figures in documents have been restored by the proposed method successfully. This method is efficiency and fast for implementing on the module of digital photocopier. © 2013 Academy Publisher.
